6.6. ESD
If the static electricity generated by various ways discharges to the module, the module maybe damaged
to a certain extent. Thus, please take proper ESD countermeasures and handling methods. For example,
wearing anti-static gloves during the development, production, assembly and testing of the module;
adding ESD protective component to the ESD sensitive interfaces and points in the product design.
The following table shows the electrostatics discharge characteristics of the module.

Within operating temperature range, the module is 3GPP compliant.

Within extended temperature range, the module remains the ability to establish and maintain a voice, SMS, data
transmission, etc. There is no unrecoverable malfunction. There are also no effects on radio spectrum and no harm to radio
network. Only one or more parameters like P
out
might reduce in their value and exceed the specified tolerances. When the
temperature returns to the normal operating temperature levels, the module will meet 3GPP specifications again.
